2. A man drove 240 miles south at the rate of 60 miles per hour. On the return trip, he drove the rate of 40 miles per hour. The

shutvik [7]

$av = \frac{v_{2} - v_{1}}{t_{2} - t_{1}}$

$t_{1} = \frac{d}{v_{1}} = \frac{240}{60} = 4 \: hours \\ t_{2} = \frac{d}{v_{2}} = \frac{240}{40} = 6 \: hours$

$av = \frac{v_{2} - v_{1}}{t_{2} - t_{1}} = \frac{40 - 60}{6 - 4} = \frac{ - 20}{2} = - 10$

$av \: speed= 10 \\ av \: velocity = - 10 \: \: north$

statuscvo [17]

The discount prices for today's housing values compared to 18 years from now with a 6% increase per year would be 108% discount. </span>
